Attention all single men out there: Don't even think about trying to put a ring on Christie Brinkley's finger! The former supermodel says that she's sworn off being a bride again ever since her fourth marriage to businessman Peter Cook ended in a nasty divorce in 2008. "I would never get married again. With what I know, I don't see why anyone would get married," Christie, who is the former wife of singer Billy Joel, tells the upcoming issue of Ladies' Home Journal. But that doesn't mean she's given up on love. "I totally believe in true love, and I think couples should celebrate their love over and over again," she admits, adding: "But right at the beginning of a relationship, I would formalize an exit strategy."
